UNITED STATES JOHN J'. CATRON, OF BONHAM, TEXAS.

FLUID DISPENSER.

Application filed August 18, 1919.

To all whom t may concern.'

Be it known that I, JOHN J. CATRON, a. citizen of the United States,residing at Bonham, in the county of F annin and State of Texas, haveinvented certain new and useful Improvements in Fluid Dispensers, ofwhich the following is a specification.

This invention relates to new and useful improvements in fluiddispensers.

The invention has to do particularly with improvements and additionsrelating to my Letters Patent No. 1,301,385, issued April 22, 1919.

One of the improved features is an automatic drain for the accumulatingcylinder whereby said cylinder is drained when the dispenser is closed;and whereby the operating mechanism is unoperatable until the dispenseris again opened and the drain valve fully closed. Such an arrangementmakes for safety as well as accuracy.

Another feature includes an accumulating cylinder to which the liquid isdelivered under pressure after having been measured thru the meter; andfrom which cylinder the liquid is discharged by gravity thru an outletvalve. This arrangement obviates air pressure in the drain hose andmakes for a smooth and rapid discharge.

One of the improvements over the aforesaid Letters Patent is thesubstitution of a hand valve for the foot operated air release valve,said hand valve being located close to the operating lever and makingfor greater convenience and simplicity. lIn this connection is alsoincluded a pressure relief valve, set to open at a given pressure andarranged so as to operate either when the controlling and air releasevalves are opened or closed.

Other features will be hereinafter more particularly brought out.

The invention will be more readily under stood from a reading of thefollowing specification and by reference to the accom panying drawings,in which an example of the invention is shown and wherein:

Fig. 1 is an elevation of a dispenser constructed in accordance with theinvention,

Fig. 2 is a side elevation of the control-` ling ,and measuringmechanism,

Fig. 3 is a front elevation of the same,

Fig. 4 is a sectional detail of the liquid control valve,

Fig. 5 is a sectional detail of the air re lease valve,

Serial No. 318,339.

Fig. 6 is a sectional detail of the master air valve,

Fig. 7 is a detail of the liquid control valve, and

F ig. 8 is a detail of the air control valve.

In the drawings the numeral 1 designates aliquid discharge pipe and 2 acompressed air delivery pipe. These pipes are arranged to be connectedwith the gasoline discharge pipe and the air pressure pipe of a suitablestorage tank, such as the storage tank shown in my co-pendingapplication filed May 2, 1919, Serial No. 294,277, which has issued inPatent No. 1,352,788, or any other equivalent structure. The pipes 1 and2 are connected to couplings 3 and 4 respectively. The couplings areconnected by a hollow cross member 5 which, however, communicates onlywith the coupling 4. .A pipe 6 including a number of elbows extendsupward in rear of the pipe 1 and is carried over and down in frontthereof to a point of connection with the hollow cross member 5. Thispipe provides a vent for the storage tank with which the dispenser isused; A normally open hand valve 7 is connected in the pipe 6 andincludes a spring pressed valve plunger 8, which is shown in its de`pressed or closed position in Fig. 5.

A liquid control valve 9 is connected to the upper end of the coupling 3and an air control valve 10 is mounted on the coupling 4. An air supplypipe 11 is bent at right angles and leads from a master air valve 12 tothe valve 10. This master valve is shown in detail in Fig. 6. This valvehas a spring pressed valve head 13 operated by a detent 14 which isengaged by the inner end of an arm 15 pivoted on the valve. The valve 9has a tapered plug 16 with an opening 17 therethru; while the valve 10has a tapered plug 18 provided with an air port 19 extending therethruand connecting with a triangular duct 20 in the surface of said valve.These valves are provided with an operating lever 22 mountedtherebetween. The upper end of the lever engages the arm 15 of themaster valve when the lever is swung to open the liquid and air valvesas in said Letters Patent No. 1,301,385.

An elbow 23 leads from the top of the valve 9 to a suitable meter 24from which a discharge pipe 25 leads to a T 26. A short pipe 27 connectsthe T 26 with an accumulatingrcylinder 28, preferably of glass. Adischarge pipe 29 leads from one branch of llO (ill

the T 26 and has an ordinary globe valve 3() connected therein. An elbow31 is connected to the end of the pipe 29 and a service Vhose 32 leadsfrom the elbow; said hose hav ing a nozzle 33 `at its end. An air ventpipe 34 leads from the top of the elbow to the top of the cylinder.

In thel center of the cylinder an overiiow pipe,Y 35 isb arranged 'andhas a section 36 leading down to an elbow 37 which is mounted on theupper end of ay section 37 leading back to the @orage tank. From the T26 a second drain pipe 38 leads to the elbow 37. Anordinary rotarycutfoff valve 39 similar to the valve 9 is connected in the pipe 38 andythis valve is normally closed to prevent the'liquid from the cylinderdraining back intothe pipe 37 A lever 40 is secured to the stem of thevalve 39 and has its lower end pivoted to the upper end of a link 41havingitslower end connected with an ear 42-proj ecting laterally from avertically slidable rod 43, said rod being supported by the link, Across-bar 45 is suitably fastened to ltheirmerside of the door 46 of thecabinet 7 inwhich themechanism is enclosed. The bar l45 is positioned sothat the door 46 must beentirely lowered and the valve 39 entirelyclosed,to permit the handle lever 22 to pass said` bar. If the valve 39remained partly open .liquid would flow back into the drain pipe37 when`it was being dispensed thus defrauding. the4 customer. Then the door isslid up. to close thecabinet the bar 45 engages the ear 42, and pushesthe link 41 upwardly therebyswinging the valve lever 40 and opening thevalve 39.

Asbeforestated the device is to beused in connection with, a suitablestorage tank. 'I"l1e,master air valve 12 is connected with an ainsupplypipe 48; which receives compressed air from a suitable source and thru@pressure reducing valve 49.

In.,using the dispenser the operator depresses theplunger 8 of the valve7 with one hand, and graspsthe handle lever 22 with the other.` hand.This closes the air vent or. exhaust. By swinging the lever 22upwardsthe valve 9 is first openedL and when thelupper end of the leverengages the arm itlie ,master air valve12 is opened, whereby compressedair flows thru the pipe 11 and past the valve 10 and thru the pipe 2 toythestoragetank. Liquid is forced out thru thepipe 1. The exact operationof these parts will be understood when considered in connection with thedisclosure in the Letters Patent No. 1,301,385 before referred to. Theliquid is forced by the compressed air thru elbow 23, pipe 25, T 26 andpipe 27 tothe accumulating cylinder 28. When a predetermined quantity ofliquid has: passed the meter the handle 22 is swung down to cut-olf Athesupply of liquid and air and the operator releases the valve 7 wherebythe air pressure below the valves 9 and 10 is vented. So long as thevalve 7 is held closed by the operator the air in the cross-member 5`and pipe 2, acts to elevate the liquid, but when the operator releasesthe valve, the air from the pipe 2 and member 5 passes out through thepipe 6.

The nozzle 33 having been placed in the receptacle to which the liquidis to be delivered, the operator opens the valve 30 whereby the liquidin the cylinder 28 flows by gravit-y down thru pipe 2 7, T 26, pipe 29,elbow 31, hose 32 and is discharged from the nozzle Itl will be seenthat an absolutely safe dispenser is had. Theease and rapidity ofoperation is, apparent and the high degree oi' accuracy makes thedispenser eflicient;

`What I claim, is:
